Electronic viewfinder apparatus and imaging apparatus
Abstract:
The electronic viewfinder 3 includes a reflective type liquid crystal display 315, a finder optical system 32, and a transmission plate 34 that transmits a part of the optical image signal collected by the finder optical system 32 therethrough and reflects at least a part of a remaining optical image signal. The reflective type liquid crystal display 315 includes a light source 311 that emits light, a liquid crystal plate 315, a reflecting plate 316, and a polarizing plate 314. The transmission plate 34 is disposed to be inclined in a direction opposite to a inclined direction of the polarizing plate such that a transmission plane 341 thereof is not perpendicular to the optical axis of the finder optical system 32.
